# Symmetry, the Bilateral Kind: Looking into Nature to Find the Balance

As we approach Autumn, things will be slowing down for us on the mountain and in the desert.  This is a very important time to still be able to go outside into Nature and find the balance.  Take pictures, enjoy the time outside and when it starts to cool down.  Notice what the plants are showing you in terms of symmetry, especially the bilateral kind.

Yes, there are different types the symmetry, but what we are all familiar with is the type that we know when we can “cut” something in half, or see the same image reflected on the other side, or even think of it as the mirror image.  However young or young-at-heart we are, this is something that we can all enjoy learning about!

Go for a walk soon and figure out what is symmetrical.  This would be also a great time to put together a math nature journal too!  Take this mushroom above, where would you place the mirror to reflect the same image?  The place that you have the mirror is called the line of symmetry.  How many lines of symmetry could this mushroom have?  One? Two? More?  Go with those questions when you go for a walk outside.  Don’t have a mirror? Take a pencil or a straight stick with you.  Place the stick where you would a mirror and eyeball it.  Where’s the line of symmetry?  🙂

If you are not able to go outside right now and explore, print out the pictures from the website, or place them up on the screen.  Get out a mirror and see where the mirror can be placed so that the same image can be seen.  Play with it!  In some cases, it might not be exactly symmetrical, but close enough.
